North West is totally adorable!

The two-year-old gave her mom Kim Kardashian a big grin on Wednesday, posing for a Twitter picture the reality star captioned "DADDY’S OFFICE."

It’s one of the biggest smiles we’ve ever seen from Kim and Kanye's adorable daughter, who’s enjoying a lollipop in the pic.

Maybe she’s excited about becoming a big sister, as the couple are expecting a baby boy in December. On last week's Keeping Up With the Kardashians, Kim revealed that North was the first person she told about her second pregnancy.

"I haven't told anyone," she told sister Khloe about her baby-on-the-way. "I told North last night, but I don't think she understands."
